The study of the elimination of Congo red dye using activated nano specimens from aqueous solution has been explored. For that liquid phase adsorption experiments are carried out. The activated nano carbon has been prepared from corn cobs. After successful development the adsorptive materials have been employed to Congo red dyes containing aqueous solutions. The influence of parameters like pH, number of adsorbents, contact time are observed throughout the adsorption studies. FTIR spectroscopy has been employed for the corn cobs to analyze the functional groups present as well as Scanning Electron Microscopy images have been recorded for the pre and post dye adsorption to know the surface morphology of the adsorbent. Agitation time has been optimized for the dye adsorbent by performing multiple experiments using these low-cost nano materials. The establishment of a kinetics model for the adsorption of dye has been accomplished. The observed parameters interestingly obey the Langmuir isotherm process for the present nanomaterials.
Key words: nano activated carbon / Congo red dye / FTIR / SEM / Langmuir plot / Kinetic model fitting
